I'm not sure if you can still get these tumblers from starbucks but that's where it was originally purchased. I'm sure there are other retailers that sell similar things. This took me a whole 15 minutes to make and I think it looks pretty cool. The mugs come with a insert template and all I did was trace it on a stiff piece of paper then glued the bands down. Trimmed the bands off at the edges and threw it up inside the cup. I kept the original template behind the one I made so I can make other inserts in the future.
I did find a computerized template once but I believe you need to have full Adobe Photoshop in order to open and use it. If you are lucky enough to have the program I think I found the template using "starbucks create your own tumbler template". That way you can do whatever you want via the computer and just print it out on a ready to cut shape.
